FOLDING GATE OR DOOR.

FEPECIFICATION forming part of Letters Patent No. 358,956, dated March8, 1887.

Application lilerl February 15, 1886. Serial No. 191.031. (No model.)

T @ZZ whom, t may concern:

Be it known that I, ACHILLE BATAILLE, of the city and State of New York,have invented an Improvement in Folding Gates or Doors, of which thefollowing is a specification.

This invention is especially available for the doors made use of inconnection with elevators for buildings, wherein it is important toclose the door and to retain the same in its closed position in orderthat accidents may not occur from the door being left open throughcarelessness.

I make use of folding diagonal bars hinged together and pivoted toupright bars or frames, and rollers for supporting the weight, and aspring or springs to close the door, and a bar is swung automatically tostil-fen the door or gate and prevent the same from yielding to lateralpressure. In connection with doors or gates formed of ranges of parallelbars crossing each other diagonally a horizontal stiffening-bar has beenmade use of; but it has been placed in position or removed by hand, andhence was not adapted to the rapid opening and closing'of elevatordoors.

In the drawings, Figure 1 is an elevation of the door or gate in itsclosed position. Fig. 2 is a horizontal sectional plan below the line a:

Fig. 3 is an elevation of ille gate in its folded condition, and Fig. 4is a sectional plan below the line y y.

The parallel bars land 2 are in two ranges crossing each otherdiagonally, and they are riveted together at the points of intersection,so that they can be spread out or folded in the manner usual in gates ofthis class.

3 and 4 are the vertical side bars of the gate. These are made hollowand rectangular in section and slotted vertically at one side to receivethe rollers 5 upon the ends of the crossbars 1 and 2, as seen 1n Fig. 2.The lower ends of the diagonal crossbars 1 2 are perma u nently attachedto the side bars, 3 and 4, by

the rivets 6 at their lower ends, so that the diagonal cross-bars swingtogether upwardly as the gate is opened by folding the bars.

I usually employ the vertical center frame composed of the bars 7 and 8,and the crossbars 1 and 2 are attached at the bottom to this centralframe, and there is a slide, ai, at the upper part of the cross-bars 1and2 that moves up and down upon the central frame, 7 and 8, as the gateis folded and unfolded.

The first part of my improvement relates to the combination, with theaforesaid folding gates, of one or more springs, 12, that act to unfoldor spread the gate and close the same. Each spring is made as a coilaround the bolt or rivet 13, and the coil is retained in place by thehead of the rivet or bolt, and the arms of the spring act against therivets or bolts 14; hence as the door or gate is folded together thespring is compressed, and as the spring expands it spreads or unfoldsthe door to close the same.

I have shown a spring at each side of the folding cross-bars; but itwill be apparent that any desired number of these springs can be appliedto the door or gate for accomplishing the desired object, and thesesprings occupy but little space, and are not likely to become caught orbroken. Should it be desired to make use of these springs for openingthe gate,

. thesame may be effected by placing the springs in the manner indicatedby dotted lilies, so that their ends or arms press in the oppositedirection to what they do when in the positions shown by the full lines.

In order to guide the door or gate in opening and closing,I make use ofthe head-bar 15, over which the upper ends ofthe bars 3 and 7 arehooked, and it is preferable to employ a roller at 16 to roll upon thishead-bar 15 and sustain the weight of the parts, and I have also shownthe roller 17 at the bottom of the side bar 3, to roll upon the iioor ora track,

The side frame 4 is provided with pivots 1S and 19 at the top and bottomends, so that the entire gate or door may be swung upon these pivots toopen the doorway to its fullest extent, asis sometimes necessary, and inorder to allow of this being done the head-bar 15 is p notched at 20 and21, to allow the hooked ends of the bars 8 and 7 to be swung clear ofthe bar 15 when the gate is open or closed. This feature of improvementis especially advantageons for allowing safes or other large articles tobe passed through the doorway.

I make use of the stiffening-bar 22, whichis pivoted at 23 upon the sidebar et of the gate, and its outer end is behind the guide-rod 24 betweenthe same and the side bar 3, and

ICO

when this stiffeningbar 22 occupies nearly a horizontal position itpasses behind the hook 25 upon the vertical bar 7, and thereby pre ventsany lateral motion at the middle part of the gate. This stiffening-bar22 is rendered automatic by the roller 26 upon the cross-bars of thegate, which acts against the cam portion 27 of said bar 22, so that asthe gate is folded the roller 26 presses beneath the cam 27 and swingsthe bar 22 upwardly, and the shape of the cam 27 is such that the outerend of the stiffening-bar 22 slides up behind the guide-rod 24 andprojects but slightly beyond it as the gate is folded and opened, andthe reverse movement takes place when the gate is unfolded and closed.

In cases where the door or gate does not 'swing upon pivots thestifening-bar 22 may be pivoted to the door-casing.

, I am aware that lazy-tongs have been made of bars crossing each otherand riveted at the Y intersections,and that these have been used infire-extinguishers, gates, and other structures, and also that springshave been employed to partially counterpoise the Weight of the parts.Therefore I do not claim any of these parts separately.

I claim as my invention- 1. The combination, With the horizontallymovingdoor or gate having diagonal folding cross-bars 1 and 2 pivoted at theirinteisec tions, of the vertical side bars, 3 and 4, to which thecrossbars are connected, the spring 12, having a coil around one of thepivots, and arms acting against the diagonal cross-bars, substantiallyas and for the purposes set forth.

2. The combination, with the horizontallymoving door or gate havingdiagonal crossbars 1 and 2 pivoted together at their intersections, andthe vertical side bars, 3 and 4, ofthe central frame, formed ofthe bars7 and 8, the rollers 16, the head-bars 15, notched at 20 and 21, and thepivots at the top and bottom ends of the bar 4, on which the gate can beswung when folded, substantially as set forth.

3. The combination, with the horizontallymoving door or gate havingdiagonal crossbars 1 and 2 pivoted together at their inten sections, ofthe vertical hollow rectangular side bars, 3 and 4, the rollers upon theends of the diagonal cross-bars and Within the hollow side bars, thevertical central frame composed of the bars 7 and 8, and the head-bar15, or track to suspend the gate, substantially as set forth.

4. The horizontally-moving door or gate having diagonal foldingcross-bars pivoted at their intersections, in combination with the sidebars, 3 and 4, the pivots to connect the cross-bars to the side bars,the head-bar or `track for suspending the gate, and the vertical framecomposed of the bars 7 and S, substan-V tially as set forth.

5. The folding diagonal ycross-bars l and 2, pivoted together, and theside bars, 3 and 4, receiving the ends of the cross-bars, in combinationwith the movable stiffeningbar pivoted at one end to the side bar 4, andswinging upwardly as the door is folded, substantially as set forth. Y Y

6. The combination, with the diagonal folding crossbars and the sidebars pivoted together, of the stiffening-bar pivoted at one end to theside bar 4, and the guide-rod upon the bar 3, behind which the other endof the stiffening-bar moves, substantially as set forth.

7. The stiffening-bar 22, having a cam, 27, in combination with afolding gate or door vhaving folding crossbars and side bars, a pivot atone end connecting the stiffening-bar to one ofthe side bars, and aroller upon one of the cross-bars to act against the cam and move thestiffening-bar as the door is opened, substantially as specified.

8. The combination, with the door or gate having the folding cross-barsand the vertical bars 3 4 7 8, of the stiffening-bar 22, pivoted at oneend to the bar 4, the guide-rod 24, behind which the other end moves,and the hook 25 on the bar 7, behind which the stiffeningbar passes, thehead-bar 15, and rollers 16, substantially as set forth.
